IIWPROVEMENT IN SASE-SUPPORTER The Schedule referred to in these LettersPatent and making part of the same.

To all whom it mii/ y concern -Be it known that I, ADDISON DAvIs, ofBoston, in .the county of Su'olk, and State of Massachusetts, haveinvented an Improved Window-Sash Supporter;

and I dohereby declare that the following, taken in` connection with thedrawings which accompany and form part of this speciiication, is adescription of my invention, sufficient to enable those skilled in theartv the sash a bent lever, having a wedge-shaped bolt,

which is pressed by a spring in between the sash and the stop-bead, in'such manner as not' only to lock the sash in any position to which itmay be raised, but, at the same time, to pressv the sash tightly againstthe frame or outer bead, so as to prevent Irattling of the window andthe entrance of rain, dust, and wind.

The drawings represent a window-sash and frame embodying my improvement.A

' A shows a front view of the sash, and part of the frame.

B, a section on the line af.

C, a section on the line zez.

adenotes the sash-frame.

b, the sash.

c, the stop-bead.

d, the outer or frame-bead. p

lThe sash is made somewhat thinner than the running space between thebeadsc d, so that it may rise and fall very easily. Y

Upon one or each stile of the sash, a bent lever, e, is hung, as seen atA, the upper part of this lever carrying a wedge-shaped bolt, f, thewedge being so shaped that, vwhen it is pressed in between the frameandthe sash, it will force back the sash, and, at the same time, bytaking firm hold' of the sash, will lock it securely in the position towhich it may have been raised.

The lower arm, g,` of each lever, extends horizontally towards thecentre of the sash-railh, its end pass ing-through a slot in a rod, i,this rod extending up through a restpiece, It, and having at top athumbplate, l, betweenwhich and the bar is a spring, m, action of whichforces up the rod i, and elevates the leverarms y, thereby pressingoutwards the bolt or bolts j, which are there held normally in positionto secure the sash at whatever height it may be.

To raise or lower the sash, the finger is placed under Vthe piece k, andthe thumb upon the platel, when, by

pressing the thumb-piece down, the bolts are retracted from between thesash and stop-beads, thereby freeing the sash, and allowing it to beeasily raised' or lowered.

A spring may be arranged to operate on the upper end of .the lever,directly opposite the bolt butl I prefer the arrangement shown, as thelocation ofthe spring enables it to act upon two levers.

The bolt fis preferably made pointed or tapering in form, as shown at A,and is made wedge-shaped, as

shown at C, so that, when pressed in between the sash' and stop-bead, itshall press back the sash against the bead d, as seen at O.

I prefer, also, to make the inner face of each stopbead c, or the faceagainst which the bolt acts, notched Y or serrated, as -seen at n, thebolt entering any one of these notches, and thereby more securelylocking the sash in position.

Itzwill be obvious that this sash-fastening and supporting-device may bemade and applied at very slight cost, that it is admirably adapted, inconstruction, arrangement, and operation, fior car-windows, and that itis an efficient instrumentality, both for 'fastening the sash inposition, and for packing the sash, to exclude dust, and prevent jarorrattling of the window.

I claim the window-sash fastener, consisting of a' s spring-lever, e,havingat its top a wedge-shaped bolt,

formed and applied as shown, so as to perform the double function oflocking the sash securely in position, and also of Wedging or pressingback the sash against the bead d, the lever having a slide-rod or otherprovision for releasing the bolt, substantially as set forth.
